Hot dogs eating hot dogs does sound kinda cannibalistic, but with such jolly grins on their faces who are we to spoil the fun? Illustrators Sarah and Colin Walsh say that making things makes them happy, and that certainly comes across in their super smily art prints. Going by the name of Petit Reve, the duo's range includes cheerful candy clouds, merry sweatband sporting water droplets, happy face snow cones and friendly best buddies, Sushi and Wasabi. On roller skates, of course. Because that's how all delicious seaweed-wrapped snacks get around.
Jump on their etsy store to browse the full range, or just add it to your favourites tab for days when your frown needs to be turned upside down.
